Question about CBWFQ & Multicast

January 20, 2008 @ 5:09 pm · Filed under CCIE Study

I found my error. Instead of using “permit udp …” I changed it and used “permit ip …” at the “access-list MULTICAST” and it start working.
R2#sh access-list MULTICAST Extended IP access list MULTICAST 10 permit ip any host 224.3.2.1 (536 matches) 20 permit ip any host 224.3.2.100 (24926 matches)
